Best Dehumidifier For Bathroom 2021

| |

Bathroom moisture and humidity can lead to problems with bacteria growth, mold and other health issues, as well as damage to walls and fixtures. Using the best dehumidifier for bathrooms will help you overcome these problems.

Home Health Living reviews the best dehumidifiers for bathrooms and shares some advice on how to choose the best one to buy.

How we did our product research

Dehumidifier performance: We researched which dehumidifier would be best at removing moisture in a bathroom. We did this by adding moisture to a bathroom (running a hot shower for 15 minutes with the window and door closed and leaving the basin and surrounding area wet) and then ran each dehumidifier in the moist bathroom for about 30 minutes. We then checked the moisture in the bathroom.

User interface and features: We looked at how easy it is to switch the dehumidifier on and for models that require a hose, we looked at how easy it is to attach the hose to the unit. We also looked at the specific features of each dehumidifier. Was it easy to know when the water tank was full and needed to be emptied?

Cost: We looked at costs in terms of upfront cost to purchase the dehumidifier but also the running costs. Often a cheaper dehumidifier isn’t always the most energy efficient. We checked to see if there was any indication of energy efficiency.

Owner reviews and reputation: We looked at reviews from other consumers online including reviews left on Amazon and chose dehumidifiers that had the highest star ratings from consumers.

How to choose the best dehumidifier for bathroom use

Dehumidifiers can be used in many rooms and areas around your home. They are used in a bathroom, basement or a crawl space where humidity is an issue. If your bathroom doesn’t have a fan, then a small dehumidifier for bathroom use is a perfect way to remove moisture.

A small bathroom dehumidifier is either compressor-based or uses Peltier technology. Peltier technology is better because it’s more energy efficient, there is less noise and the dehumidifier is lightweight.

It’s important to know that dehumidifiers remove the moisture in the air, but they cannot cool down the air like an air conditioner can.

Not all dehumidifiers are the same. When choosing the best dehumidifier for bathroom use, there are some differences you will need to be aware of between each of the units.

Differences to look out for are the technologies used, the moisture extraction ability and the water tank capacity. The larger the tank capacity, the less often you will need to empty the water. This is particularly important for those who live in very humid climates.

Best budget option

The Pro Breeze Mini Dehumidifier is a popular option for those wanting a small but efficient dehumidifier for a small room or space such as a bathroom, small laundry or baby nursery.

The Pro Breeze dehumidifier uses Peltier technology, meaning that it can extract more moisture than other dehumidifiers while still using the same amount of power. The technology improves its efficiency.

The water tank can hold up to 16 ounces of water. The unit extracts up to 8 ounces per day.

Operation is 23 watts.


Very efficient unit


Whisper-quiet technology

Best compact dehumidifier for bathroom

The Ivation IVADM35 dehumidifier is an excellent choice for bathrooms and other small rooms, and especially recommended for use in areas with high levels of humidity.

The unit uses both Peltier and ERS technologies. ERS technologies help to balance the temperature of the Peltier element, which is typically hot on one end and cold on the other. By balancing the temperature, the unit is able to extract more moisture using the same power consumption as a unit without the ERS technologies.

It can extract up to 12 ounces of moisture per day, and the water tank has a capacity of 22 ounces. This is greater than most other dehumidifiers currently on the market.

Once the water tank is full, the LED indicator light changes from blue to yellow which indicates it needs to be emptied. When the water tank is full, the unit shuts off automatically.


ERS technologies allows more extraction of moisture

Larger tank capacity

Ideal for those living in very humid climates

bathroom dehumidifier review

Do dehumidifiers work in bathrooms?

Yes, by using a dehumidifier in your bathroom you are helping to prevent problems with moisture, mold and bacteria growing. This is because the dehumidifier will remove the moisture in the bathroom. Moisture is what is need for mold and bacteria to grow.

Now that you know that dehumidifiers do work in bathrooms, it’s time to choose one to buy. Read our bathroom dehumidifier reviews to find the best brand and model dehumidifier for your bathroom.

What size dehumidifier do I need for my bathroom?

Your best option is a 30 pint dehumidifier which is perfect for a bathroom but can also be used in other rooms in your home. You can read more about dehumidifier standards as set out by the U.S. Department of Energy.

A small dehumidifier that extracts up to 8 ounces of moisture per day is a suitable size for your bathroom. These dehumidifiers have water tanks that typically hold up to 16 ounces of water.

A common error many people make is buying the wrong type of dehumidifier, one that is too small or not powerful enough for the room they need to dehumidify. The best dehumidifier for bathrooms won’t be suitable for a large basement. And a large dehumidifier better suited to a basement may be too noisy and large to be placed in a bathroom.

The dehumidifiers we have reviewed in this post are all suitable sizes for a bathroom. They are smaller than your average dehumidifier unit.

Type of bathroom dehumidifier

Small dehumidifiers for bathrooms typically use a compressor or Peltier technology. Peltier technology is used to control the temperature- the Peltier heat pump cools the surface and condenses the water vapor from the humid air. Peltier technology means no moving parts are required, and operation is much quieter when compared with a dehumidifier that uses a compressor. It also makes the unit lightweight.

Efficiency levels

When deciding on a dehumidifier for your bathroom, it’s a good idea to know how much moisture the unit can extract before the water tank needs to be emptied. It’s also important to know how much power the unit consumes. By knowing these two pieces of information, you can determine whether the dehumidifier is efficient. If you can find a unit that extracts a larger amount of moisture but at the same power consumption level of a dehumidifier with a lower extraction, then you know you have found an efficient dehumidifier. This is important for the environment, and for your wallet!

Water tank capacity

If your bathroom dehumidifier has a large water tank, then it means you will not have to empty the tank as often as a bathroom dehumidifier with a smaller tank. This is because the water tank can hold more moisture. If you live in a humid climate, then it’s recommended you find a bathroom dehumidifier that has a larger tank capacity.

Common complaints about dehumidifiers

The most common complaint that people make about dehumidifiers is that they are not working properly, simply because there isn’t much water in the water tank. Sometimes there may be a fault with the unit itself, but usually the problem is that the room is not very humid to begin with. Another problem could be that the wrong type of dehumidifier has been purchased for that particular room or space. As mentioned earlier, a small dehumidifier for bathroom use won’t be suitable for a large basement.

Another typical complaint about dehumidifiers is the noise level. Just like any other appliance, a dehumidifier will make noise. Whether the noise is loud or not is subjective, but it is often described as sounding similar to an air conditioner. Keep this in mind when purchasing a dehumidifier- expect some level of noise.

One final word…

These are our top picks of the best dehumidifier for bathrooms, and our reviews of each dehumidifier. Your choice will largely depend on your budget, your bathroom’s humidity level and your personal preference.

Once you start using your new dehumidifier, you will notice a difference to the level of humidity in the bathroom. It will improve the air quality and reduce mold, bacteria and germs that breed in humid rooms.
